To all whom, it may concern.-

Be it known that 1, RANDALL A. PALMER, a citizenof the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Shaft-Hangers, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object certain new and useful improvements in pressed steel shaft-hangers; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation. Fig. 2 is a View in front elevation. Fig. 3 is a view in section longitudinally of the hanger. Fig. 4c is a cross-section on the line 4 4:, Fig. 3. Fig. 5 is a detail view, in inverted plan, of the fastening-plate, showing the frame in horizontal section. Fig. 6 is a detail view in perspective of the contact-block. Fig. 7 is an enlarged view, in vertical central section, at right angles to that shown in Fig. 3.

The purposes of my invention more particularly relate to the provision of a shafthanger that shall be self-alining, the same being adjustable both laterally and vertically, and, furthermore, to provide a hanger of lighter structure than those heretofore employed and which shall be of superior economy in cost of manufacture.

I carry out my invention as follows:

In the drawings, a represents a supportingframe, the same being made in two parts and having supporting-arms 1 and 2, the two portions of the frame being united when the hanger is in place above the hanger-box by means of a connecting-bar Z) and at the lower extremities thereof by a connecting-bar 0, said bars being preferably U-shaped in cross-section. The frame a is engaged at its upper end or at the upper sides of the arms 1 and 2 upon detachable supporting-plates, (indicated at (1d,) said plates being secured to the structure thereabove in any suitable manner. By making the supporting-plates independent of the frame the frames and plates may be shipped in a knockdown condition. The dealer may also keep a desired number of plates and a desired number of frames in stock and from his stock select a suitable frame and suitable plates and make up these portions of the hanger. One of these plates is shown in detail in Fig. 5, the same being constructed 'with a downwardly-projecting shoulder e, to

which the said arms may be bolted, the plate being also provided with flanges f f on each side of the shoulder e, to which the arms 1 and 2 are respectively bolted, as indicated at g. A connecting-bar it may also be bolted through the flanges f f to strengthen the upper portion of the arms, the bolts atg 9 uniting both the upper ends of the arms and the extremities of the connecting-plate h to the plates (Z.

The hanger-box consists of an outer shell, (indicated at 6,) and 1' represents the inner shell of the box, the same being made in two parts longitudinally divided, said inner shell being provided with an interior lining, as of Babbitt metal, (indicated at Z4.) Intermediate the extremities of the intermediate shell of the box I provide a convex ring or cylindrical bearing, (indicated at l,) which may be suitably united at its lateral edges to the inner shell of the box, as indicated at m m. In cross-section the convex bearing Z is areshaped, and the adjacent portion of the outer shell 2' of the box is similarly constructed adjacent to the convex bearing, as at a, the construction of the convex bearing and of the outer shell of the box adjacent thereto being the one the complement of the other, so as to form essentially a ball-and-socket joint, the one with the other. In this manner the inner shell of the box will adjust itself to the shaft independently of the outer shell of the box and independent of the hanger-frame. To prevent the inner shell of the box from rotating with the shaft, the convex bearing may be provided with an indentation (indicated at p) to engage in the corresponding indentation (indicated at q) in the outer shell of the box. The outer shell of the box is constructed to form an oil-chamber between it and the inner shell of the box, as indicated at r, and rings (indicated at s s) are shown surrounding the shaft, the rings depending into the oil-chamber to lubricate the shaft in a well-known manner, the inner shell of the box and its interior lining being constructed with recesses (indicated at t t) in the upper half of the in- .ner shell to receive the said rings.

The box is made adjustable in the supporting-frame by means of set-screws, there being, preferably, four in number, (indicated at u,) the upper set screw being preferably passed through the connecting-bar 7/. Underneath the outer shell of the box a is a contactblocl; 0, secured upon the outer shell of the hanger-box, against the extremities of which the two set-screws at the sides of the hanger impinge, said. block being formed at its extremities with flat surfaces, against which the lateral set-screws may impinge in the vertical adjustment of the hanger. Said block is also adjusted with a flat lower face, against which the lower set-screw impinges in the lateral adjustment of the hanger-box. The two portions of the hanger-frame, together with the connecting-bars Z) and 0, are preferably provided with nuts w set thereinto to receive the setscrcws "It.

It is preferred to make the various parts of my improved shaft-hanger of pressed steel.

It will be seen that the indentations 7) and r are all of limited width and that the indentation 1) of the convex bearing fitting into the indentation q of the outer shell thereby prevents the" inner shell from turning with the shaft. It will be seen, furthermore, that since the inner shell of the box contacts only with the outer shell by essentially a ball andsoclzet-joint connection the said inner shell may readily adjust itself to the shaft independently of the position of the outer shell.

hat I claim as my invention is- 1. In a shaft-hanger the combination of a supporting-frame, a hanger-box supported in said frame comprising an outer shell, an inner shell spaced from the outer shell, and a cylindrical bearing between said shells. said outer shell and said bearing having a ball-andsocket-joint connection the one with the other, the inner shell of the box being self-adjusting upon the shaft independent of the position of the outer shell of the box, and independent of the hanger-frame, and means to adjust said box laterally and vertically.

2. In a shaft-hanger the combination of a supporting-frame, a hanger-box supported thereby comprising an outer shell, an inner shell spaced from the outer shell, and a convex cylindrical bearing between the outer and the inner shells encircling the inner shell intermediate the ends thereof and secured thereto, the said bearing and the outer shell forming a ball-and-socliet-joint connection the one with the other, and means to adjust said box laterally and vertically.

3. In a shaft-hanger the combination of a supporting-frame made in two parts, an independent detachable supporting-plate for each of said parts, a hangenbox supported upon said frame comprising an outer shell, an inner shell spaced from the outer shell, and an intervening cylindrical bearing, said outer shell and bearing having a ball-and-socketjoint connection the one with the other, means to connect the two parts of the frame, and means for adjusting the hanger-box vertically and laterally, said frame, plates and hanger- 5 box formed of pressed steel.

4. In a shaft-hanger the combination of a supporting-frame constructed with two separable parts, an independent supporting-plate for each of said parts, a hanger-box supported by said frame and made self-adjusting therein, each. of said supporting-plates constructed with a downwardly-projecting shoulder, and withiianges on each side of said shoulder, substantially as described.

5. In a shaft-hanger the combination of a supporting-frame, a hanger-box supported thereby comprising an outer and. an inner shell, means to connect the two parts of the frame, means for adjusting the hanger-box vertically and laterally, said hanger-box provided with a cylindrical bearing between the outer and inner shells secured at its lateral edges to the inner shell, said cylindrical bearing arcshaped in cross-section intermediate its edges, the outer shell being correspondingly formed adjacent to the arc-shaped portion of the bearing to form essentially a balland-soclret-joint connection the one with the other.

6. In a shaft-hanger the combination of a supporting-frame, a hanger-box supported thereby comprising an outer and an inner shell, means to connect the two parts of the frame, means for adjusting the hanger-box vertically and laterally, said hanger-box provided with a cylindrical bearing between the outer and the inner shells secured at its lateral edges to the inner shell, said cylindrical bearing arc-shaped in cross-section intermediate its edges, the outer shell being correspondingly formed adjacent to the arc-shaped portion of the bearing to form essentially a ball-and-socket-joint connection the one with the other, said bearing and outer shell formed with corresponding indentations the one to engage the other to prevent the inner shell of the box from turning.

7. In a shafthanger the combination of a supporting-frame, a hanger-box supported thereby comprising an outer and an inner shell, an adjustable contact-block secured upon the outershell and underneath said outer shell, said block having flat end surfaces and a flat lower face, setscrews to impinge against the end and lower surfaces of said contact-block, and an additional set-screw to engage the upper portion of the hanger-box, whereby the hanger-box may-be adjusted vertically and laterally.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
